Blissus occiduus
Western Chinch Bug
Blissus occiduus, the western chinch bug, is a phloem-feeding true bug (Hemiptera: Blissidae) that is a significant pest of warm-season turfgrasses, particularly buffalograss and zoysiagrass. The species exhibits strong host preference hierarchies, with buffalograss being the most preferred host followed by zoysiagrass, though it can survive and reproduce on a broad range of grasses including agronomic crops. Field studies have documented inconsistent control with neonicotinoid insecticides, with thiamethoxam showing particularly rapid degradation in buffalograss tissues compared to imidacloprid and clothianidin.

Bombus bifarius
Two-form bumblebee
Bombus bifarius is a eusocial bumble bee of the subgenus Pyrobombus, first described by Cresson in 1879. Recent genetic research (2020) has clarified its taxonomy: what was historically considered a single species with two color morphs (red-tailed 'bifarius' and black-tailed 'nearcticus') has been split into two cryptic species. True B. bifarius is now restricted to the red-tailed form found in the southern Rocky Mountains, while the black-tailed and variable forms belong to the sister species Bombus vancouverensis. The species is small-bodied and has been identified as one of only two bumble bee species known to use pheromones in kin recognition.

Bombus cryptarum
cryptic bumblebee, Cryptic Bumble Bee
Bombus cryptarum is a widespread bumblebee species native to the northern hemisphere, occurring across Europe, Asia, and western North America. It belongs to the subgenus Bombus sensu stricto, a species complex of morphologically similar and difficult-to-distinguish bees. The species was only recently confirmed in the British Isles and its complete distribution remains unclear due to ongoing taxonomic uncertainties. Several subspecies have been described, including the endangered B. cryptarum florilegus in Japan and the recently described B. cryptarum pallidocinctus.

Bombus vancouverensis
Vancouver Bumble Bee, Vancouver Island Bumblebee
Bombus vancouverensis is a eusocial bumblebee of subgenus Pyrobombus, widespread across mountainous regions of western North America. The species was long treated as synonymous with Bombus bifarius, with most historical literature on bifarius actually referring to vancouverensis. Genetic studies completed in 2020 confirmed their distinct status, with true B. bifarius being exclusively red-tailed and geographically restricted, while B. vancouverensis is polymorphic and broadly distributed. It is one of only two bumblebee species known to use pheromones for kin recognition.

Boreidae
snow scorpionflies, snow fleas
Boreidae, commonly known as snow scorpionflies or snow fleas, are a small family of approximately 30 species of scorpionflies in the order Mecoptera. These tiny, wingless insects are notable for their unusual winter activity period, emerging on snow surfaces during cold months when most other insects are dormant. Recent molecular research indicates Boreidae are more closely related to fleas (Siphonaptera) than to other scorpionflies, a finding that has significant implications for understanding the evolutionary relationships within Mecoptera. The family has a boreal and high-altitude distribution in the Northern Hemisphere, with species documented across North America, Europe, and Asia.

Brachycaudus
Short-tailed Aphids
Brachycaudus is a genus of aphids in the family Aphididae, commonly known as short-tailed aphids. The genus contains approximately 43 species distributed worldwide, including significant agricultural pests such as B. helichrysi (peach leaf curl aphid) and B. rumexicolens. Species in this genus exhibit remarkable evolutionary lability in life cycle strategies, with transitions occurring between monoecy on woody hosts, heteroecy (host alternation), and monoecy on herbaceous plants. This flexibility contradicts the traditional assumption that aphids cannot regain primary woody hosts once lost.

Brachycaudus helichrysi
leaf curl plum aphid, leaf-curling plum aphid, peach leaf curl aphid
Brachycaudus helichrysi is a small aphid species first described by Kaltenbach in 1843. Molecular studies have revealed it comprises two cryptic sibling lineages, B. helichrysi H1 and H2, which are morphologically indistinguishable but genetically divergent and differ in life cycle strategies. H1 follows a typical heteroecious cycle with sexual reproduction on plum trees, while H2 consists largely of obligate asexual superclones with some sexual populations on peach trees in India.

Brachymyrmex species-d
Brachymyrmex species-d is an undescribed species within the genus Brachymyrmex, a group of small, inconspicuous ants commonly known as "rover ants." The genus Brachymyrmex contains multiple cryptic species that are difficult to distinguish morphologically, and species-d represents one of several lineages awaiting formal taxonomic description. Like other members of the genus, it is expected to be minute in size and adapted to disturbed habitats, though specific biological details remain undocumented pending formal study.

Brachynemurus sackeni
Sacken's Antlion
Brachynemurus sackeni is a widespread, arid-adapted antlion species in the family Myrmeleontidae. Phylogeographic studies using mitochondrial COI sequences have revealed it comprises a cryptic species-complex with two distinct lineages that diverged approximately 3.8–4.7 million years ago, potentially associated with Neogene mountain-building events. This represents the first documented cryptic species-complex in Myrmeleontidae. The species is attracted to mercury-vapor lights and has been documented in juniper chaparral habitats.

Brasiella
Brasiella is a genus of small to very small tiger beetles (Cicindelidae) containing more than 50 described species. Formerly treated as a subgenus of Cicindela, it is now recognized as a distinct genus based on morphological and behavioral differences. The genus is predominantly Neotropical in distribution, with species occurring from Panama and the West Indies south to Peru and Argentina. Most species are cursorial (running) beetles adapted to open, sandy or muddy habitats. Brasiella argentata is among the most common and widespread species, though it appears to represent a species complex distinguishable primarily by male genitalic characters.

Caenocholax fenyesi
Caenocholax fenyesi is a strepsipteran parasitoid in the family Myrmecolacidae, notable for extreme sexual dimorphism and heterotrophic heteronomy—males and females occupy different hosts throughout their life cycles. Females are endoparasites of Orthoptera, while males parasitize ant larvae and pupae, primarily Solenopsis invicta (red imported fire ant) in the United States and related native fire ants in Mexico, Central America, and parts of South America. The species has a sporadic distribution across the southern United States, Central America, and South America, with three recognized cryptic subspecies that are morphologically similar but genetically distinct. Adult males are free-living with a lifespan of only hours to a few days, severely constraining dispersal and contributing to genetic bottlenecking effects.

Camponotus vicinus
Bicolored Carpenter Ant
Camponotus vicinus is a large, conspicuous carpenter ant distributed across western North America from Alaska to Mexico and east to Texas and Manitoba. Unlike many carpenter ants that nest in wood, this species typically nests in soil under stones and other objects, though it also uses fallen, decomposing logs in higher elevation conifer forests. It is a prominent scavenger and predator in terrestrial ecosystems and is one of the most abundant ground-dwelling arthropods in California's higher elevation conifer forests. The species belongs to a genetically diverse species complex with cryptic diversity, including localized populations of conservation interest such as an undescribed species endemic to the Channel Islands.

Carcina
oak long-horned flat-body moths
Carcina is a small genus of micromoths in the family Peleopodidae, containing four species distributed across Europe and the eastern Mediterranean. The genus is notable for its members' distinctive appearance: pastel pink or purple wings with yellow markings and exceptionally long antennae relative to body size. The most widespread species, C. quercana, serves as host for the specialized parasitoid wasp Venanides carcinae. A recently described species, C. ingridmariae, was discovered in 2025 after being misidentified as C. quercana for over a century, representing a rare case of overlooked colorful European moth diversity.

Carcinocephalus
Carcinocephalus is a genus of dwarf spiders (Linyphiidae: Erigoninae) characterized by distinctive cephalic modifications. These minute sheet-web building spiders are among the smallest arachnids, typically measuring only a few millimeters in length. The genus name refers to the crab-like or projecting head structure found in males. Members of this genus construct flat, sheet-like webs and are generally associated with ground-level or low vegetation habitats.

Cardiocondyla venustula
Larger Black Sneaking Ant
Cardiocondyla venustula is a small myrmicine ant native to Africa, with introduced populations in the Caribbean and North America. The species belongs to the C. shuckardi group and exhibits an intermediate reproductive strategy among congeners, with wingless males that attack freshly eclosing rivals but rarely engage in lethal combat with established competitors. Instead, males establish and defend small territories within their natal nests. The species shows considerable genetic diversity across its native range, with multiple mtDNA lineages detected in South Africa, Angola, and Côte d'Ivoire that are morphologically and nuclearly similar, indicating a complex taxonomic history.
